Trumpets in the Bible
In the tenth chapter of the Book of Numbers, it states that Yahuah instructed Moses to make two trumpets made of silver for the purpose of guiding and directing the people of Israel in the wilderness. They were to be blown by the priests to call them to assemble, when they were to break camp and move to a new location, to proclaim the beginning of festivals and new months, and to alert them during times of war. The trumpets were to be used in different ways and with different number of blasts to indicate to the camps what Yahuah wanted them to do accordingly.
Numbers 10:1 And the Yahuah spoke to Moses, saying: 2 “Make two silver trumpets for yourself; you shall make them of hammered work; you shall use them for calling the congregation and for directing the movement of the camps. 3 When they blow both of them, all the congregation shall gather before you at the door of the tabernacle of meeting. 4 But if they blow only one, then the leaders, the heads of the divisions of Israel, shall gather to you. 5 When you sound the advance, the camps that lie on the east side shall then begin their journey. 6 When you sound the advance the second time, then the camps that lie on the south side shall begin their journey; they shall sound the call for them to begin their journeys. 7 And when the assembly is to be gathered together, you shall blow, but not sound the advance. 8 The sons of Aaron, the priests, shall blow the trumpets; and these shall be to you as an ordinance forever throughout your generations. 9 “When you go to war in your land against the enemy who oppresses you, then you shall sound an alarm with the trumpets, and you will be remembered before Yahuah your Elohim, and you will be saved from your enemies. 10 Also in the day of your gladness, in your appointed feasts, and at the beginning of your months, you shall blow the trumpets over your burnt offerings and over the sacrifices of your peace offerings; and they shall be a memorial for you before your Elohim: I am Yahuah your Elohim.”
